Abstract
An improved method and system for performing path-level access control evaluation for a structured document in a collection, where the structured document includes a plurality of nodes and each of the nodes is described by a path, is disclosed. The method comprises providing a cache for temporarily storing a cache entry for a path associated with a node of the plurality of nodes, receiving a query that includes a request to access the node, checking the cache entry for the path associated with the node, and determining whether to grant access to the node based on the cache entry.
